M3933/25-33S

Overview

The M3933/25-33S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a nominal attenuation of 7 dB with a frequency range extending from 0 Hz to 12.4 GHz. The component features SMA connectors and supports a maximum power rating of 2 W. Designed for rugged environments, it operates within a temperature range of -55°C to +125°C. This unit complies with MIL-DTL-M3933 standards and is classified as a Qualified Products List (QPL) item.

Feature Summary

• Qualified Products List (QPL) compliance ensuring strict military-grade quality control
• Screened construction for enhanced environmental durability
• Fixed 7 dB attenuation value for precise signal level management

Applications

• Military communication systems requiring certified RF components
• Aerospace test and measurement equipment
• Defense radar signal processing chains

Procurement Notes

Verify that the specific suffix 'S' corresponds to the screened variant required for your application. Confirm that the QPL status meets your program's contractual obligations. Ensure SMA connector gender compatibility matches your system interconnects. Validate that the 2 W power rating aligns with peak signal levels in your circuit design.

Selection Notes

Select this model when a fixed 7 dB reduction is necessary within the 12.4 GHz bandwidth. Consider the SMA interface for standard high-frequency connections. Evaluate the -55°C to +125°C operating range against your environmental constraints. Compare against other M3933/25 variants if different attenuation values or higher frequency ranges are required.

Part Context

This component belongs to the M3933/25 series of connectorized attenuators. It shares the same form factor and general specifications as other models in the family, differing primarily in attenuation value and frequency limits. The series is widely used in defense electronics where standardized military specifications are mandatory for procurement and integration.
